I like the dual purpose aspect of it myself. If i went to brushless I would go with a large low kv motor, like the kb 45 10xl (1300kv) on 4s lipo and gear it for around 30mph in 2nd gear. That way low gear would be still slow, and it would have a bunch of torque. And with a slowly spinning motor the effecientcy would be ok, and so would the temps. I would most likely use a MM and an external bec to run all of those servos well...
